>>2755373>What you're telling me is that all of the 4232 dungeons are hand crafted?Of course not, but their entire layouts were already stored on the install CD, which is what allows us to analyze how they were generated. What you find is that all dungeons consist entirely of those identically-sized square blocks; there's nothing between them and no random parts connecting them. The only difference between any two dungeons, even main quest dungeons, is which blocks were placed in the grid. The blocks themselves have no random elements except for the enemies and loot that spawn within them. Their layouts, the locations of quest rooms, and the paths to reach them within each block are always identical. Every block has exactly two possible quest locations, except border blocks which have none.
Basically, from almost anywhere you stand in a dungeon, everything you can see in all directions is part of the same handcrafted segment. Only when you cross a door to another block will you notice a difference, and even then you will only see parts of those two blocks at the same time. With the exception of the eight doors (two on each edge of the square) leading out of your current block, you will never find a room, corridor, or quest location that was not hand placed within that block.
To illustrate this it's a good idea to look at some full dungeons. Here's a dump of the Abibon-Gora region:

>>>>>>b001>b012 w002 b006>b006 n041 b011>>>>>>b005 "b" means Border, "w" means Wet, and "n" means Normal. So this dungeon has one flooded block on the north end and one dry block south of it. They are connected by two doors along their shared edge. Recall that each block has eight doors leading outside, so there are six border blocks - each one sealing off an unused edge of one of the two main blocks. Border blocks are special because you cannot traverse them like other blocks.
